In the title compound, C(17)H(20)Cl(2)N(4)O, the piperazine ring adopts a chair conformation and the dihedral angle between the pyridazine ring and the benzene ring is 36.3 (1)°. In the crystal, weak C-H⋯O and C-H⋯(N,N) inter-actions help to establish the packing, which also features short inter-molecular Cl⋯Cl contacts [3.331 (2) Å].
متن کامل3-Chloro-6-{4-[3-(trifluoromethyl)phenyl]piperazin-1-yl}pyridazine
The title compound, C(15)H(14)ClF(3)N(4), was synthesized from 3,6-dichloro-pyridazine and 1-[3-(trifluoro-meth-yl)phen-yl]piper-azine. The piperazine ring is flanked by 3-chloro-pyridazine and 3-trifluoro-methyl-phenyl rings and adopts a chair conformation, whereas the 3-chloro-pyridazine and 3-trifluoro-methyl-phenyl rings are planar, with maximum deviations of 0.0069 (13) and 0.0133 (14) Å, ...
متن کاملComputational Investigation on the Structure and Performance of Novel 4,7-dinitro-furazano-[3,4-d]- pyridazine Derivatives
Seven novel energetic 4,7-dinitro-furazano-[3,4-d]-pyridazine derivatives were designed, and their optimized structures and performances were studied by density functional theory (DFT) at B3LYP/6-311g(d,p) level. The detonation performances were estimated by the Kamlet-Jacobs equations. The results show that these compounds have high crystal densities (1.8181.925 g·cm−3), detonation velocities ...
